When cardiac output is reduced, central venous pressure and pulmonary capillary pressure are high, there is a high oxygen difference between capillary blood and venous blood, leading to hemodynamic disorders. If not treated promptly, the patient often dies quickly.

1. Recognizing signs of cardiogenic shock

Cardiogenic shock is a condition in which the heart suddenly cannot pump blood to meet the body's needs. Cardiogenic shock is rare, but if left untreated, it can be life-threatening or even fatal. Possible signs of cardiogenic shock include:
Sweating, pale or pale skin, cold limbs Loss of consciousness, low or unmeasurable blood pressure Patient has rapid breathing with shortness of breath, tachycardia Less or less urinary retention Most cases of heart hypoxia are due to angina, and when oxygen-rich blood cannot flow to the heart chambers, the heart muscle weakens and causes cardiogenic shock. Besides, other possible causes of cardiogenic shock are:
Myocarditis or heart valve infection Heart failure Drug overdose that affects the heart's pumping ability Arrhythmia or cardiac tamponade Embolism Lung Other factors such as: age and sex (the older you get, the greater the risk of cardiogenic shock and women are more likely to have cardiogenic shock than men), history of heart failure or heart attack, blockage of a major artery , diabetes, high blood pressure.

2. Characteristic hemodynamic disturbances in cardiogenic shock

Characteristic hemodynamic disturbances in cardiogenic shock include:
Decreased cardiac output index < 2.2 L/min/m2. High pulmonary capillary pressure, with a reading > 15 mmHg, is a sign of hemodynamic dysfunction. High central venous pressure > 10 mmHg and There is a high oxygen difference between capillary and venous blood (DA-VO2 greater than 0.55 ml O2/l) due to disturbances in cardiogenic shock due to impaired cardiac function . Therefore, in the treatment of cardiogenic shock, in addition to symptomatic treatment and resuscitation, it is necessary to find and solve the cause of cardiogenic shock early.

3. Prevention of cardiogenic shock

To prevent cardiogenic shock, it is important to prevent and treat the causes of cardiogenic shock early, including:
Controlling high blood pressure: Controlling blood pressure is a method to prevent heart attack and risk cardiogenic shock. Dietary changes: Eat less cholesterol and fat, especially saturated fat. If you can't change your diet, your doctor may prescribe cholesterol-lowering medications. Don't smoke: Regular smoking increases the risk of a heart attack. Maintain a healthy weight: Being overweight increases your risk of heart attack and cardiogenic shock. Exercise regularly: Regular exercise reduces the risk of heart attack, besides, exercise also helps control weight as well as diabetes and reduce stress.
